1、安装CUDA、cuDNN、Anaconda、Tensorflow-GPU和pyTorch：
准备安装文件：
ubuntu@ubuntu:~$ ls
anaconda3 NVIDIA-Linux-x86_64-440.31.run
Anaconda3-5.1.0-Linux-x86_64.sh snap
cuda_10.0.130_410.48_linux.run 公共的
cudnn_samples_v7 模板
Downloads 视频
examples.desktop 图片
libcudnn7_7.4.2.24-1+cuda10.0_amd64.deb 文档
libcudnn7-dev_7.4.2.24-1+cuda10.0_amd64.deb 下载 libcudnn7-doc_7.4.2.24-1+cuda10.0_amd64.deb 音乐 NVIDIA_CUDA-10.0_Samples 桌面
安装后用 nvidia-smi 查询GPU参数：
ubuntu@ubuntu:~$ nvidia-smi

在 Anaconda下创建虚拟环境来安装cuDNN， TesnorFlow 的 GPU 版，以及pyTorch等软件。
ubuntu@ubuntu:~$ source activate py36
(py36) ubuntu@ubuntu:~$ conda list

2、使用Anaconda创建虚拟环境：
查看已安装的虚拟环境：
conda info -e
指定Python版本创建虚拟环境：
conda create --name py36 python=3.6
查看虚拟环境安装过的依赖包：
conda list -n py36
给虚拟环境安装依赖包：
conda install -n py36 cudnn
激活虚拟环境：
source activate py36
退出虚拟环境：
source deactivate
给虚拟环境安装OpenCV-Python：
conda install -n py36 --channel https://conda.anaconda.org/menpo opencv3
